3 Models
Model methodology escape justice as follows.
Escape Evacuation Equipment
Escape rope
- □
Rope length. integer marked in meters (m)
/ □
Rope Diameter. integer marked in millimeters (mm)
Example.
Length 6m, diameter 9mm escape rope, the model for TS-6/9.
4. Technical Requirements
4.1 Structure
Escape rope core rope should wrap Shengpi cored rope structure. One end of the rope should bight structure and connected to a safety hook the other end optional
With seat belts.
4.2 appearance quality
Escape rope surface should be free of any mechanical damage phenomenon, the whole rope thickness uniformity, consistent with the structure.
4.3 length and diameter
Escape rope diameter of not less than 8mm. Nominal value with the factory control, length tolerance of ± 0.2m, diameter tolerance is ± 0.5mm.
4.4 breaking strength
Minimum escape rope breaking strength of not less than 10kN.
4.5 Elongation
When the load reaches 10% of the minimum breaking strength and elongation of the safety rope shall be not less than 1% and not more than 10%.
4.6 safety hook
4.6.1 Safety hooks shall be of metal material and provided preventing safety device mistakenly open, the safety device should be locked reliably.
4.6.2 safety hook through strength testing, body and safety hook safety device shall not obvious deformation, fracture, loss and other anomalies.
4.7 seatbelt
4.7.1 belt material should be cotton or synthetic material. Bandwidth 40mm ~ 80mm, with a thickness of 1mm ~ 3mm, with a long
1000mm ~ 1800mm, and the length can be adjusted with a buckle by user bust size.
4.7.2 After the strength test the seat belt webbing and buckles and other components shall cause rupture phenomenon.
5 Test methods
5.1 structure and appearance quality inspection
Visual method to escape justice by the structure and appearance quality inspection.
5.2 length and diameter measurement
With universal length measuring measuring rope (ending both ends of the whole rope escape rope not included in length) and diameter. The length and the same rope
3 times the diameter measurements are required, the arithmetic mean of the three.
5.3 breaking strength and elongation test
Carried out according to the method specified in GA494 escape rope breaking strength and elongation testing.
5.4 Test safety hook
5.4.1 by visual inspection reports and viewing the material approach to safety hook structure and materials to be checked.
5.4.2 The safety hook and pull both ends of the upper and lower jigs machine connected safety device in the locked state. Rally stretching speed is set at
30mm/min, and then applying a tensile load 10000N on the hook to keep 5min.
5.5 Test seat belt
5.5.1 by visual inspection reports and viewing materials approach to belt structure and materials to be checked. Then measured with a universal measuring tool
Belt length, width and thickness, measure any 3 points, the arithmetic average of three points.
5.5.2 The two ends of the belt of the upper and lower clamping jig Rally. Rally stretching speed is set at 100mm/min, and then applied to the sample
Plus 6376.5N tensile loads, while maintaining 5min.
